: just got an e34, and having issues

hey everyone, i just purchases a 91 525i 5 speed. i bought it last week and it was fine, but now i'm having some issues.

my rear passenger side window is cracked slightly open, i cant open or close it, my wipers dont work, i cant crack my sunroof but i can open it fully (sometimes when i try to close it, it takes a second before it starts closing), and my radio keeps searching for a station signal for all the regular popular radio stations, it plays, but sometimes it has a cracking noise/is not too clear.

i have already replaced the GM, RM, and CCM with ones i found on another 91 525, but i am still having issues.

i checked every fuse there is, all have power going through them

then i checked the fusible link thats easily accessible and its fine

the other fusible link i couldnt really get to because it was so low...

i sprayed some greaser on the wipers to see if it would help any and that did not work

now i did realize on the one touch on my sunroof was much easier to do than before and that puzzled me because i remember it was suppose to be one hard touch for it to open or close all the way

any ideas?

Hows the battery connection? Any build up?

check the other fusible link...
and check them with a multimeter, not by eye.

It sounds as if you have a grounding issue, either corroded or loose ground. I am not familiar with the ground wire locations but it is probably a point where you have multiple ground wires going to a single bolt on the chassis.

Loose or corroded connections will act as high resistance not allowing for the current to reach the component you are energizing (such as a window motor, etc) as you keep trying to activate that component, the connection will heat up and sometimes, eventually complete the connection and allow the component to work. I hope this gives you another thing to look at
